Log4Shell: log4j Remote Code Execution vulnerability

No violationsstackroxcriticalbuilddeploy

Alert on deployments with images containing the Log4Shell vulnerabilities (CVE-2021-44228 and CVE-2021-45046). There are flaws in the Java logging library Apache Log4j in versions from 2.0-beta9 to 2.15.0, excluding 2.12.2.

Rationale: These vulnerabilities allows a remote attacker to execute code on the server if the system logs an attacker-controlled string value with the attacker's JNDI LDAP server lookup.
Remediation: Update the log4j libary to version 2.16.0 (for Java 8 or later), 2.12.2 (for Java 7) or later. If not possible to upgrade, then remove the JndiLookup class from the classpath: zip -q -d log4j-core-*.jar org/apache/logging/log4j/core/lookup/JndiLookup.class
